Tarot is excellent for receiving clarity on problems or issues that logic can't handle (most of the important ones in life!). Relationships, negotiations, work dynamics, office politics, family matters, spiritual well-being, forks in the road, what-if scenarios ... Tarot gets asked every question under the sun!
Even though having your question spelled out in words can help you during the interpretation phase, don't worry if you can't find words for your issue. If you can feel it and imagine it in any way while shuffling and picking your cards, the cards will be apt and well worth studying. Because it is structured to report on "energies" active in the current situation, whether you have a question in words or not does not substantially affect the fall of the cards.
Tarot is not designed to handle certain kinds of questions. Questions asking for data or a yes/no answer are not suitable for a Tarot reading. Ask for understanding and advice about some situation or issue.
